Marble Chips And Hydrochloric Acid Observations

Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas.

Marble chips and hydrochloric acid observations.

Hydrochloric acid to react with the marble chips independent variable marble chips to react with the acid dependent variable stopwatch to accurately time the experiment spatula to handle the marble chips measuring cylinder to precisely measure out different concentrations of hydryochloric acid electric balance to measure the mass g of the marble chips bung. Repeat the experiment with 20g of the same marble chip size and 20cm 3 of the acid made up to 40 using distilled water. A demonstration of the procedure for investigating the effect of concentration on the reaction between hydrochloric acid and calcium carbonate marble chips. Compare the slopes of the two graphs.

Finding the rate of reaction of marble chips and hydrochloric acid changing the surface area. The rate of this reaction can be changed by changing the size of the marble chips. There are many variables that affect. Hydrochloric acid marble chips the experiment the aim of this experiment is to find out how different variables affect the rate at which the reaction between marble chips caco and hydrochloric acid hcl takes place.
